🔌 IEC C19 Power Cable
 
(250V AC • 15A • IEC 60320 C19 to NEMA 5-15P • High‑Current Connector)

The IEC C19 power cable is a heavy‑duty cord designed for high‑power equipment. It features a C19 female connector (rectangular, 3‑prong) that mates with a C20 inlet on servers, UPS systems, PDUs, and enterprise‑class hardware.
 
🔧 Cable Form
Voltage rating: 250V AC
Current rating: 15A (sometimes up to 20A depending on region/certification)
Connector type: IEC 60320 C19 → NEMA 5-15P
Shape: Rectangular, 3‑prong, keyed to prevent mis‑insertion
Cable gauge: 14AWG
 
🖥️ Compatible Devices
🟦 Data Center & Enterprise Hardware
Rack‑mounted servers (HP ProLiant, Dell PowerEdge, IBM System x)
Blade enclosures and modular compute chassis
Enterprise storage arrays (EMC, NetApp, HPE 3PAR)
🟦 Power Infrastructure
Uninterruptible Power Supplies (UPS) above 2kVA
Power Distribution Units (PDUs) in server racks
High‑capacity switches and routers
🟦 Other High‑Power Equipment
Professional workstations and rendering rigs
Industrial equipment requiring 15–20A draw
High‑wattage power supplies (1500W+ PSUs, e.g. Corsair AX1600i)
 
✅ Common Uses
🔌 Connecting servers and storage arrays to rack PDUs
🧩 Linking UPS systems to downstream power strips or PDUs
🧪 Supporting high‑wattage PSUs in workstations and mining rigs
🧵 Essential entry in the data center power ecosystem
 
🧠 Signal Format
⚡ Input: 100–240V AC (region dependent)
🔋 Output: Pass‑through AC, up to 15A continuous
🔌 Connector: Rectangular C19 → NEMA 5-15P
🔁 Not interchangeable with C13/C14 (smaller 10A connectors)
 
⚠️ Things to Watch Out For
📉 Must match current rating — don’t substitute C13 for C19 in high‑draw systems
🔌 Connector is rectangular 3‑prong — won’t fit C13/C14 inlets
🧯 Always confirm device label (e.g. “AC IN: 250V 15A, C20”) before use
📏 Cable gauge matters — use 14AWG full 15A loads
 
🛠️ Quick Tips for Beginners
🧭 Look for C20 inlets on servers, UPS, or PDUs — that’s where C19 plugs in
🔌 Confirm connector: rectangular 3‑prong C19 (larger than C13)
🧪 If device won’t power, check for loose fit or mismatched C13 vs C19
🧯 Label clearly to avoid mix‑ups in dense rack environments
